JESSE VINCENT, OF DETROIT, MICHIGAN, ASSIGNOR TO PACKARD MOTOR GAB COM- PANY, OF DETROIT, MICHIGAN,A CORPORATION OF MICHIGAN.

MOTOR-VEHICLE.

To all whom it may concern Be it known that I, JnssnG. VINCENT, a citizen of the United States, and resident of Detroit, VVa-yne county, State of Michigan, have invented certain new and useful 'In'rprovements in Motor-Vehicles, of which. the following is a specification.

This invention. relates to motor vehicles, and. particularly to the mechanism for controlling the motor.

Que of the ohjects of the invention is to simplify the mechanism for the control of the motor and particularly of the carburetor thereof, and to place said niechanisn'i within easy reach of the operator of the vehicle With this and other objects in view, the in vent-ion will be described in connection with the drawings, which form a part of this specification, and in which,

Figure 1 is a side elevation of parts of a motor vehicle, including the steering column and carburetor and connecting devices;

Fig. 2 is a view similar to F ig. 1, showing --the connecting devices in a different position;

Fig. 3 1s a front view of a part of the steering column shown. in Fig. 1;

Fig. leis a top view of the control board mounted on the steering column shown in Fig. 1'; v

Fig. 5 is an underneath view of said control board, showing parts in section and Fig. 6 is a section approximately on the line 66 of Figs. 4 and 5.

Referringto the drawings, .10 represents part of a motor vehicle frame, upon which the steering column 11 and the dash 12 are supported; The vehicle motor is also supported upon this frame in the usual manner, and the intake pipe 13 of the motor is shown in Figs. 1 and 2. TllfidllOlZOl carburetor 14: is supported from the intake pipe 13 andis provided with a main air. intake passage 15 controlled. by a butterfly valve 16, and an auxiliary'air passage 17 controlled by a spring operated puppet who 18. As

- shown in Figs. 1 and 2, the butterfly valve 16 may be moved from its open and closed positions by the arm 19 and rearwardly extending rod 20, and the tension of the springs 21 of the valve 18 may be regulated by a Wedge shaped cam 22 operated by a rearwardly extending'rod 23.

The dash 12, hereinabove referred to, and

the inclined fioor board 2 1 assist in supporting the steering column 11, and adjacent the upper end of the steering column is a bracket 25 which may be in the form of a control board, and which is positioned, as will be seen in the drawing,.within easy reach of the operator of the vehicle. Upon this control board may l)0 arranged various switches and other control devices, such as the ignition switch 26, electric light buttons 2-7, etc.

At the low-n: end of the steering column 11 is another bracket marked 28, and mounted to slide in the brackets 25 and 28 is a-control rod 29, which is adapted to he moved longi. tudinally by the operator of the vehicle through a rack and pinion mechanism 30, shown in detail in Figs. 5 and 6. This mechanism includes a rack 31 formed in. the npperend of the control rod 29, and a. pinion 32 keyed to a shaft 33 mounted in the bracket or control board 25 and extending through one of the sides of said control board. A hand Wheel 34. is secured to the projecting shaft 33, whereby the operator may rotate the shaft 33 and thereby move the rod 29 longitudinally. The rod is retained in adjusted position by a spring pawl 35 acting on a. ratchet 36 formed inthe upper end of the rod 29, shown particularly in Figs. 5 and (l.

It will be seen also that this rack and pinion mechanism and the pawl and ratchet device are mounted in a supporting casing 37. which is itself secured to the control board. 25, as by screws 38.

Adjacent the lower end of the steering column is a bra cket 39 which independently suppo two bell cranks 40 and 11, the

former olltwhich has its arm 42 connected to the rearward end of the rod 23, andthe latter of which has its'arm 43 connected to the rearward end of the rod 20. The rearward. end of the rod 20 is also secured-to a spring 44-, which thereby yieldingly holds the main air intake passage 15.

mate bya spring 49 surrounding the rod and adjustable thereon by the nut 50. The

arm 51 of the bell crank 40 operates between,

' forwardly to give the maximum tension on the springs 21, the finger 45 .will begin to operate upon the arm 46, and the continued downward movement of the rod 29 will carry with it the rod 20 and consequently close the butterfly valve .16, It will therefore be seen that the longitudinal movement of tlie'rod 29 downwardly will first operate upon the valve sprir' 21 until those springs-"have reached li'mii maximum ten sion, and then act upon the valve 16 to close Iii-other words, the rod :ZWactuates. sez iotim the de I vices controlling the two valves of the can bureter, thus increasing the richness of the mixture of the carbureteras the rod 29 is moved downwardly, and vice'versa.

ig.-1, the carbureter valves are shown with tin lightest tension on the springs 21 and witlr the main air intake 15 Wide open.' In, 2, the rod 29 has been I moved downwardlfto the .ia'rthest eztent,

and the Wedge 22 has increased the tension on the spring 21 'to themaxiinuni, and the valve 16 has practically closed the main air, intake passage 15, so that the carburetor will deliver the richest possible mixture, which is What isusually required in startin ilthe motor in cold Weather.

aving thus described my invention, What Iclaim and desire tosecure byLctters Patent is,

1. In a motor vehicle the combination with the steering column, a control rod I mounted thereon, and a device at the upper 3 said rod, of a carburetor having 'of valves, rods for controlling said valves, levers to which said 'rodsare end of the steering column for actuating a plurality connected,

and means on said control rodxfor yieldingly engaging one ofsaid levers and for positively engaging the other of said levers. 2. In a motor vehicle, the combination With the steering column, a control rod mounted thereon, and a device at the up per end of the steering column for actuating said rod, of a carbureter having aplu rality of valves, rods for controlling said valves, levers to which said rods are connected,.a spring device on" said control rod for engaging one of said levers and a rigid device on said, rod for engaging the other of said levers.

3. Ina motor vehicle, the combination with the steering column, a control rod mounted thereon, and a device at the upper end of the steering column for actuating said rod, of a carhureter having a plurality of valves, rods-for controlling said valves, levers in which said rods are con.- nee-ted, and means on said control rod for engaging said levers 88? 1L2fi91'2.
